An air regiment of the Western Military District stationed in the Tver Region in central Russia has completed its rearmament with the generation 4++ Su-35S fighter jets under the defense procurement plan, the District’s press office told TASS on Wednesday.

"The fighter regiment of the Western Military District has completed forming a squadron of generation 4++ Su-35S super-maneuverable fighters for its permanent deployment in the Tver Region. Overall, the manufacturing plant in Komsomolsk-on-Amur delivered six planes in July under the defense procurement plan," the press office said in a statement.

The new Su-35 fighters will replace the air regiment’s outdated aircraft pool. Military pilots and technicians accepted the new aircraft on the premises of the manufacturing plant in the Khabarovsk Region in the Russian Far East. The pilots underwent re-training in Lipetsk where they used special simulators to learn to perform aerobatic maneuvers at full speeds and loads.

Previous reports said that three Su-35 fighters had been delivered to the air regiment in the Tver Region under the defense procurement plan.
